Conduction, where particles within a conductor gain energy as they heat up and vibrate more vigorously passing energy onto adjacent particles as they collide. Convection, which only occurs in fluids, as f...

Use SUVAT equations to find height, S, when final velocity, V, is 0: s = ?u = 50 m/sv = 0 m/sa = -9.81 m/st = Not necessaryRecall: v² = u² +2as s = -u²/(2a) = -2500/(...

This is a common class of question concerning projectile motion and the independence of orthogonal forces.
First the student should sketch the problem an label the forces, In doing this they will see...

The photoelectric effect is the observation that when light of a certain frequency or higher is shone onto a particular metal surface, electrons are emitted from the metals surface. Let's consider a devic...

F = qv x B = qvB sin(O). q is the electrons charge = 1.6x10^-19 C. v is the electrons speed = 2x10⁵ ms^-1 . B is the magnetic field strength = 0.5 T. ...
